again so some people can see what sakurai said on this
"One such feature users commented on was the ability to invite your companions into your house and stroke their heads and faces to raise your affinity level. Basically, you bring them into your room—regardless of whether you’re married or not—and give them a rubdown. Even I chuckled to myself the first time I played: “What is this, Pokémon? Nintendogs!?” Some reviewers, however, went one step further and said, “We don’t need this!”
I’m not a big fan of dating sims myself, so I can’t say I don’t understand their disinterest to a certain extent. At the same time, however, the feature in question doesn’t have any impact on one’s ability to complete the game, so if it bothers you so much, then don’t use that feature.
Say you buy a boxed lunch and it happens to contain a variety of foods, including one you hate. Even if you love everything else about the meal, are you going to single out the one food you dislike and lambast the entire meal for it? What about the people who happen to love that food? Is a meal only worth it insofar as it caters to your each and every preference?
Developers include all sorts of bonus features simply because they want to provide a little something extra for the fans. Even if one were to remove these bonus features from the game, it doesn’t mean that would “make room” for something else. That isn’t how it works."
